ing or otherwise marring theglass, or the loupe may be wornsatisfactorily bypersons ,not wearing eyeglasses. j

Numerous types of loupes have been used heretofore, but greatdifficulties have been experienced due vtoitheit'aict thatjthe eyeglasslenses have been considerably scratched,

parties not. wearing eyeglasses considerable difficulty has-beenexperienced in maintaining the loupe in'positi'on for use.

An important advantage of my invention is to provide a loupe'havingfrictional protective means carried; thereby so that the same may beused withease without ruining a pair of eyeglas es orstraining a per-,

sons eye in case he does not wear spectacles.

Another important object of'tmy invention is to provide a jewelers'loupeof this character which is strong, durable, very simple and inexpensivein construction, and which is well adapted to the'usage for which it. isdesigned.

Other objectsand advantagesof the in- I vention will become apparentduring the course of the following description;

In the drawings, wherein like numerals are employed to designate likeparts throughout the same,

Figure 1 is a side elevation illustrating the protective covering woundtightly and having the adjacent edges ofthe coils contacting with eachother. I

Figure 2 is a side elevationshowing the protective covering wound withthe adjacent edges in spaced relation.

Figure 3 is a View illustrating a modification of the invention whereinthe protec tive covering is in the form of a split tube which is slippedon the rings, and g 1 Figure 4: is a view illustrating the loupe appliedon an eyeglass.

9 which are provided with aligning screw- 4- I l \A i i A i I threadedopen ngs passing tnerethrough, whereby a suitable screw may be insertedto .lirnily clamp the rim about a lens 10. I

having the rim'7; split, various-types of enes may be used, for thepurposes asgwill be readily understood. A pair of bars' 11 and 12 areused to maintain the. rings 51and {a :e V v i V o in substantiallyparallel spaced, relation to.

each other and in such'positions as to lie substantially parallel tothe. rim 7 and the lens 10. Of course, all of the frame work thus fardescribed maybe constructed of suitable wire orniaterial that will befound I moat satisfactory.

In accordance with my invention the rings 5 and 6 are provided withfrictional protective means which may be any cellulose composition, suchas z'ylonite,or rubber, or"

infact any material that will prevent the metal parts from scratchingthe lens when the loupe is used in conjunction with apair of spectaclesThe covering 13, as'is shown in Figure 1 of the. drawings, may be woundtightly and in such a manner that the edges of the coils willcontactsothat a continuous surface will be presented. This type of covering isparticularly well adapted for use on a pair of spectacles and willprovide a surface that will positively not be injurious to the mostdelicate lens. l

' In Figure 2 is shown the covering 14, being so wound around the ringsthat the adjacent edges of the coils will be disposed in spaced relationto each other so that a small groove, or the like, 15, is formed. Thistype is especially well adapted for use by persons not Wearingspectacles, and it will. be seen that the ring5 may be placed againstthe eyes, thereby causing the muscles of tie face surrounding the eye tohold the composition or rubber split and slipped over the rims, as isclearly shown in the drawings. Of course, it it is desired groovessimilar to the grooves 15 may be cut into the tube 16 to facilitate itsuse without spectacles.

It will thus be seen that I have constructed a jewelers loupe that willinsure perfect satistaetion to the user, at the same time attordingconvenient means that may be used either on an eyeglass or without, ineither care without injurv to the glass or the eye of the user.

It to be raider-stood that the term of my invention herewith shown anddescribed to be taken as the preferred embodiment of the same, and thatvarious cl'iangcs in the shape, size and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the sub-joining; claims.

Having;- thus descril'ied my invention, what 1" claim as new is:

l. A jewelers loupe ol the class described, comprising; a rim a lenstherein, riiigs disposed in spaced relation thereto, and a triotionalprotective strip spirally coiled about said rings, the adjacent edges ofsaid. coils being in spaced relation to each other to provide spiralgrooves in said protective coverinn.

In a device of the character described, a lens, means for holding thelens, a metallic ring spaced from the lens and substantially parallelthereto, a spacing member connecting the ring and lens holding means,and a non-1netallic covering on the ring having antislipping raised andlowered portions on its peripheral surface.

3. In a device of the character described a lens, means for holding thelens, a pair of metallic rings spaced from, the lens and sub stantiallyparallel thereto, a spacingmember connecting the lens holding; means andrings, and a non-metallic covering on the metallic rings havinganti-slipping raised and lowered portions on its peripheral suriace.

In a device of the character described, a lens, means for holding thelens, a ring spared from the lens and substantially parallel thereto, aspacing member connecting; the ring and lens holding means, and aprotective anti-slipping covering on the ring said covering havingseparated friction grooves transversely arranged on its peripheral.surtacos.

5. In a device oi the character described, a lens. means For holding thelens, a ring spaced from the lens and substal'itially parallel thereto,a spacing member connecting the ring and lens holding member, and aprotective anti-Flipping member spirally coiled around the ring.

(3. In a device of the character described, a lens, means for holdingthe lens, a ring spaced from the lens and substantially parallelthereto, a spacing member connecting the ring; and lens holding member,and a protective anti-slipping member spirally coiled around the ringwith a. space left between each coil.
